Electrolyte disorders: patients may have electrolyte disorders causing vomiting after dialysis, and electrolyte disorders can be corrected in time. 3. Abnormal blood pressure: low blood pressure or high blood pressure may occur in the process of dialysis, which can cause vomiting symptoms, and at this time it is necessary to give antihypertensive or blood volume supplementation to raise the pressure according to the blood pressure.
